Object manufactured as physical representation of mesh model

A control system to control a mechatronic positioning system to manufacture an object, comprising:

• an input interface for accessing data or instructions which define a structure of a mesh model, wherein the mesh model is a volumetric mesh model comprising mesh elements which define a surface of the object and which define a lattice structure which fills at least part of an interior volume of the object, wherein the mesh elements comprise straight edges which are connected to each other via respective nodes;
• a control interface to the mechatronic positioning system;
• a processor subsystem configured to, via the control interface, control the mechatronic positioning system to manufacture the object as a physical representation of the mesh model, wherein the mechatronic positioning system comprises an end effector, and wherein the control of the mechatronic positioning system comprises:
• a. with the end effector, holding a straight rod, wherein the rod physically represents an individual edge of the mesh model;
• b. with the end effector, causing the rod to assume a position and orientation relative to a previously manufactured part of the object at which position an end of the rod contacts or is in welding proximity of an end of at least one previous rod of the previously manufactured part of the object;
• and
• c. welding the end of the rod to the end of the at least one previous to physically establish a node connecting two or more individual edges of the mesh model;
• and repeating steps a)-c) for respective individual edges and nodes of the mesh model to iteratively build up the physical representation of the mesh model.
